Research Themes +
Energy Technologies Area (ETA) researchers are continually building on the strong scientific foundation we have developed over the past 50 years. We address the world’s most pressing climate challenges by bringing to market energy-efficient innovations across the buildings, transportation, and industrial sectors. ETA is at the forefront of developing better batteries for electric vehicles; improving the country's aging electrical grid and innovating distributed energy and storage solutions; developing grid-interactive, efficient buildings; and providing the most comprehensive market and data analysis worldwide for renewable technologies like wind and solar.
Strategic Initiatives +
The Energy Technologies Area (ETA) Strategic Plan is the guiding force for our research and development for the next ten years. It clearly charts a path toward clean-energy solutions and focuses on five detailed Strategic Initiatives. The Plan provides an in-depth look at how ETA is accelerating research to provide affordable, clean energy to all while accomplishing deep, economy-wide decarbonization, looking to avoid a rise in global average temperature while simultaneously developing solutions to increase humanity's resilience to extreme weather volatility.

Abstract

Multilayer structures of YBa2Cu3O7-x-PrBa2Cu3O7-ywere prepared, using pulsed laser deposition,withthe a-axisoriented normal to the surface of a variety of (001) substrates. Structural characterization of these films by X-ray diffraction (XRD), transmission electron microscopy (TEM) and helium ion beam channeling reveal a highly ordered microstructure similar, if not better, in quality to that obtained in the best c-axis oriented films. Studies of the surface morphology by scanning electron microscopy (SEM) show a very smooth surface with a total absence of the outgrowths commonly seen in c-axis oriented films. We observe that while the a-axis oriented films grown on (001) substrates show no a-b axis twinning, the films are composed of 0.01-0.1 µm sized domains that have the Y(Pr)Ba2Cu3O7-x c-axis oriented along thesubstrate (100) or (010) in-plane direction. Superconducting transition temperatures, for current transport the plane of the films, consistently exceed 80 K and are found to increase with the size of the domains. © 1991 IEEE
